Save route settings so that they are valid after network restart
Create a file named route-eth0 in the/etc/sysconfig/network-script/directory.
Vi/etc/sysconfig/network-script/route-eth0
Add the following content to this file:

192.168.1.0/24 via 192.168.0.1

Restart network verification

 
/Etc/rc. d/init. d/network contains the following lines:

# Add non interface-specific static-routes.
If [-f/etc/sysconfig/static-routes]; then
Grep "^ any"/etc/sysconfig/static-routes | while read ignore args; do
/Sbin/route add-$ args
Done
Fi

That is, add the static route to the/etc/sysconfig/static-routes file.
 
For example, join:
Route add-net 11.1.1.0 netmask 255.255.255.0 gw 11.1.1.1

The static-routes format is
Any net 11.1.1.0 netmask 255.255.255.0 gw 11.1.1.1
